Re: [PATCH 03/17] mmc: mmci: Mask IRQs for all variants during runtime suspend

In runtime suspended state, we are not expecting IRQs and thus we can
safely mask them, not only for pwrreg_nopower variants but for all.

Obviously we then also need to make sure we restore the IRQ mask while
becoming runtime resumed.

So, what happens when this patch is applied, and a SDIO card is attached
which expects to receive interrupts at any moment?

Given that I've run into this during the last week with a SDHCI controller,
I'm not that thrilled with other interfaces doing the same broken thing.
